i Application filed July 16, 1904. Serial No. 216,851-

To all whom it 11i/ty concern:

Be it known that I, FRANCIS ARTHUR MILLS, a citizen of the UnitedStates, residing at the city of Lawrence, in the county of Essex andState of Massachusetts, have invented certain new and usefulImprovements in Shuttle-Checking Means for Looms; and I do herebydeclare the following to be' a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The following description, read in connection with the accompanyingdrawings, will enable any one skilled in shuttle checking and lockingmechanism for looms to understand my invention and to practice it in theform in which I prefer to employ it 5 but it will be understood that myinvention is not limited to the precise form and details of constructionherein illustrated and described, as various modifications and changesmay be made without exceeding the scope of my invention and the claims.

Referring to the drawings, Figure l shows in top view'the leftshuttle-box of the lay, having the binder located at the back thereofand the shuttle in position having just come in contact with mypneumatic binder. Fig. 2 shows a like view, the shuttle having fullyentered the shuttle-box and in contact with the picker and picker-stickto actuate an impact-strap to force the binder against the shuttle tocheck and lock it. Fig. 3 shows a side view of the same. Fig. 4 is alongitudinal section of the binder, taken on the line 4 4 of Fig. 5,showing my novel pneumatic'and corrugated cushion-shuttle binder. Fig. 5is a cross-section of the same on the line 5 5 of Fig. 4 showing theair-Chamb ers. Fig. 6 shows the front side of the left end of the boXand means for adjusting the impact-strap to cause the shuttle to bestopped and locked at a predetermined position in the shuttle-box. Fig.7 shows the protection-finger arranged to operate the binder between thelatter and the impact-strap. Fig. 8 shows the same in top view.

The object of my present invention is to arrange an impact-strap so asto yieldingly force a shuttle-binder against the shuttle. To cause thisoperation, I provide a novel ar- I the shuttle at a predeterminedposition within the shuttle-box, and the means for effecting this I willnow describe.

An impact-strap 4 is arranged at the back of the binder 7 and has oneend 5 connected to the lay or shuttle-box, passing across a movable part6 of a binder 7 around the picker 8 and picker-stick 9 and fastened toadjustable means whichl is connectedto the box or lay, so that theimpact of the shuttle upon the picker or picker-stick will cause imipactupon the strap to cause itto force the f binder against the shuttle.

While I have shown the impact-strap as crossing the path of thepicker-stick above the lay, obviously that part of the strap whichreceives the impact of the picker or pickerstick caused by the shuttlemay be dropped beneath the lay around the picker-stick and adjustablyconnected to the lay.

The binder is pivoted to the lay and forms one side of the shuttle-boxand is constructed as follows: The contact-face of the binder may be ofleather-or a thin sheet of metal 10, fastened upon the binder, and thebinder is preferably made in sections and riveted together at itsfulcrumed end. Between said contact-facing and the binder is seen apneumatic cushion 11 to coact with the shuttle. This pneumatic cushionedshuttle-binder, as seen in the drawings, produces its pneumatic functionupon the shuttle by one or more airchambers 12, preferably parallel withthe binder, so as to produce a pneumatic function upon the shuttle whenthe latter strikes it and when the said binder is forced against theshuttle by the impact-strap. Coacting with the pneumatic chamber orchambers the face of the pneumatic cushion which joins the binder hascorrugations 13 to increase the cushion or pneumatic effect when theshuttle strikes the binder and when' the binder is IOO forced againstthe shuttle by the effect o1 the impact of the shuttle upon the pickeror picker-stick upon said strap.

Referring to the impact-strap, the means for adjusting it to provide forthe stretch of the strap and wear of the picker by the impact of theshuttle, so as to stop the shuttle at a predetermined position in theshuttlebox, are seen in Figs. 1, 2, and 6, and consists of a revolublestud or post 14, secured by a clamp-nut to a bracket 15, which is boltedto the lay, and to said post the strap is fastened and wound around it,so that by loosening said nut on the stud or post the latter may beturned to wind up or let out the strap for its adjustment. I alsoprovide means for laterally adjusting the fulcrumed end of the binder,and for this purpose the binder-fulcrum 16 is an eccentric, and byloosening a nut 17 and turning the eccentric the binder may be movedfarther in or out .from the opposite side of the shuttle-box. Thisadjustment of the shuttle-binder at its fulcrumed end is to give more orless lifting action to the protection mechanism and pneumatic pressureupon the shuttle.

Looking at Fig. l it will be seen that the shuttle has struck the swellof the pneumatic binder with a cushion effect, thus giving easy entranceto the box. The shuttle having entered fully in the box, as seen in Fig.2, it will be noticed the pneumatic binder has been compressed, whichalso compresses the corrugated surface of said binder, caused by theimpact of the shuttle upon the picker, and thereby cause a pullingaction of the impactstrap which has forced said binder against theshuttle with a pneumatic locking function upon the shuttle to lock it atthe desired position in the shuttle-box.

The protection device is of the usual form, having the protection-finger18, its shaft 19, and spring 2O for forcing the finger against thebinder, and looking at Figs. 1, 2, and 3 it will be seen that theprotection-finger is in engagement with and pressing upon the impactshuttle-locking strap, said strap or band being shown located betweenthe. projectionfinger and the movable end of the binder, so that whenthe shuttle strikes the pneumatic bind er, forcing its free end out,will cause said strap to be frictionally drawn under springpressurebetween said binder and the protection-finger, thereby aiding inchecking the shuttle while traveling in the box. The protection-finger,however, may be located between the shuttle-locking impact-strap and thebinder, as seen in Figs. 7 and 8,which will cause said strap to forcethe protection-finger against the shuttle-binder and said binder againstthe shuttle to lock it.

Looking at Fig. 4 it will be understood that the impact-facing of thebinder will have .in its contact with the shuttle a yielding functiondue to the elasticity of the rubber and a yielding function due to itspneumatic function, the combined effect of both these yielding elementsbeing to cause the binder rto conform to the shape of the shuttle whiletraveling and at the limit of its travel in the shuttlebox.
